MARGIN-GAGE DEVICE.

To aZZ whom it may concern:

Be it known that I, CrmnLnsSrIno, citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Margin-Ga e Devices, of which the following is a specifh cation.

This invention relates to margin gage devices and particularly to the construction of the right and left hand margin controlling stops of a typewriting machine.

The invention has for an object to provide a novel and improved construction of margin gages freely slidableupona typewriter carriage and adapted to be locked in position by means upona relatively fixed part, together with means for releasing said gages when it is desired to write beyond the established margin.

A further object of the invention is to provide an improved structure of margin stop slidably mounted upon a toothed bar and having means to engage and move a stop pawl into locking engagement with the teeth of said bar.

Another object of the invention is to present a: novel constructionof right margin gage freely slidable upon a toothed bar and having a pivoted member adapted to engage the teeth of said bar when engaged by a cooperating lock lever.

Other and further objectsand advantages part, such asa bell ringer or line of the invention will be hereinafter set forth and the novel features thereof defined by theappended claims. y i

writing machine in any preferred manner. The'frame 11 carries at the rear a guide rod 12 upon which the carriage 13 is slidably mounted, for instance by a sleeve 14. The front of the carriage is supported by a truck or carrier wheel 15 which travels upon a rod 16 pivotally mounted at its opposite ends in the frame 11. Thecarriage 13 is pro vided with a fixed'gage bar 17 having at one end the holding teeth 18 upon its under face and formed at its opposite end with holding teeth 19 upon itsupper face.

The margin gage 20 is freely slidable upon the bar17 and disposed to establish a margin atfthe left hand end of is rotatab-ly mounted in the carriage 13 in the usual manner. If desired this gagemay support a paper guiding finger QQ'eXtending upward at the front of the platen and carrying a'bearing roller23. The gage is ad justably held in position by a spring 24 secured thereto and frictionally bearing upon thebar17. This gageis also provided with a depending angularly disposed lip or toe 25 mounted to. cooperate'with a stop pawl 26. This pawl is pivotally mounted at 27 upon the rod 16 and formed beneath its pivot with a holding face 28 disposed to contact with a restoring springQQ carried by an extension 30 from the pivoted rod 16. In the the platen 21 which travel of the carriage whenthe lip 25 engages'the tooth 31 of the pawl 26 it is lifted into locking engagement with one of the teeth 18 upon the bar 17. If it be desired to release this margin stop in order to write beyond the left margin on the paper, the

pawl may be moved out of engagement with the tooth'by rocking the rod 16. For this purpose any preferred means may be pro.- vided, for instance, a depending, lever 32 secured to one end of the rod, and the latter,

also be provided with a restoring spring secured thereto and to the carriage frame, as shown in Fig. 1. When the pawl is so rocked away fromthe gage bar the spring 29 restoreslit to lowered position and also permits the lip to ride over the tooth thereof in the return travel of the carnage.

The right. hand margin gage is construoted .to'cooperate with the bell ringer and line lockand comprises a slide casing 35? mounted to freely move on the gage bar 17 and it may be provided with a paper finger 36 carrying a'feed roller 37 and simi larin construction to the'finger 22 before described: Uponthis'casing a pawl 38 is pivoted at 39 and the oppositely extending arms 40 thereof are each provided with a holding tooth 41-adapted to seat in 'the teeth 19 upon the upper face of the bar 17 These arms are normally held in a horizontal plane and in disengaged position by a spring 42 secured to the casing and bearing upon the upper face of the arms. The lower portion or toe 43 of this pawl is disposed to successively engage and operate a bell ringer lever 44 and a line lock lever 45. v This toe 43is formed with an angularly disposed inclined face 46 at one side which acts to cam away or move these levers out of its path in the return travel of the carriage. 7

Any preferred form of bell ringingmechanism may be used, and a desirable construction is herein shown in which the lever 44 is pivoted-at 47 upon a bracket 48 depending from thebase plate 10 and provided with a lifting 49 extending beneath the hammer arm 50 which is mounted upon the pivot 47. The lever 44 is restored to normal position by a spring 51' extending from a lug 52 thereon to the baseplate. The free end ofthis lever is also formed with a curved face 53 to engagethe toe 43 which rocks the lever in the return-travel of the carriage. The arm 50 is provided with the hammer 54 to contact with a bell 55 and is restored to initial position by a spring'56 extending therefrom to a projection 57 from the bracket 48.

Any ordinary character of line locking mechanism ,may be used, but a preferred form is herein illustrated in which the lever 45 is pivotally mounted at 58 upon the looking lever 59 and has its lower end formed with a notched tooth 60 disposed to embrace a plate 61 carriedby a bracket 62 extended from a universal bail This bail is mounted on the sector 64 in the usual manner and actuated in a rearward reciprocating move ment by'a shoulder 65 upon a typebar 66, as shownsin Fig. 2. I

The locking lever 59 is pivoted at 67 upon the sector and normally held in contact with a stop 68 thereon by a spring 69 secured at one end to the sector and at its opposite end to saidlever. The contact lever 45 is adapted to yield outwardly when engagedbythe toe 43 in the return travel of the carriage and is restored to vertical position by a sp'ringTO disposed between the contact and locking levers, and such restoringmovement is limited by a stop 71 below the pivot of the contact lever, as shown in Figs. 2 and If it be deemed to write beyond. the right handmargln, as in the addition of letters to complete a word, the contact lever 45. may

be moved out of engagement with thetoe of the pawl 88 by the tail 72, formed onthe stop pawl 26 and disposed at the rear of the contact lever. Thisaotion is effected by rocking the rod 16 which releases both margin gagesand the line locking leveris withdrawn from the bail by its restoring spring so that all parts are left free for further I writing.

bar and this pawl being mounted upon the rocking release rod'also controls the, release of the line locking mechanism through its tail disposed to engage a member thereof. Both of the margin stops are freely movable upon the gage bar and may be readily slid into the desired position to establish the margins. ld hen starting a line the carriage is moved toward the right until the left hand gagelifts the stop pawl into engagement with the toothed barwhich locks the gage in position to form a stop. If it be desired to write to the left of this margin, as when making marginal notes, a backward pressure upon the handle of the rocking rod shifts thestop pawl out ofengagementjwith the bar and leaves the carriage free for further travel toward'the right. As soon as this pressure is relieved the parts are automatically restored to initial position and in the carriage travel toward the left the pawl will yleld to. permit the lip of the gage to ridelever and its engagement therewith rocks the pawl'carried uponjthegage so that one of its armsengages the teeth upon the upper face of the gage ban; The continued travel of the right hand gage causes itto operate the line lock lever and the contact with. either face of the depending arm of the pawl locks the gage to form a stop. When it is desired to; writebeyond the right margin the rock shaft is operated to bring the tail of the stop pawl into contact with the, contact lever of the line lock and shift the same out of engagement with the pawl upon the right hand gage. Such action releases the line lock and the stops leaving the'carriage free to be moved in either" direction. When the pawl upon the rlght hand gage has moved to the, left of the contact lever of the line lock and Y the carriage is to be restored to initial position, theinclined face of this pawl moves the lever out of its path without affecting the line locking lever'which is released from the universal bail by its restoring spring whenoutsofengagement with the gage pawl. The curved face of the bell ringer lever contacting with the incline upon the pawl permits the former to be depressed without actin; uponthe bell hammer. The control and release of both of the margin gages, as well as'the line lock mechanism, is effected by the single rock shaft so that the several devices are disposed in cooperative relationto perform their functions.
